The system of equations are $\"\"$ , $\"\"$ and $\"\"$ .

Solve the system of equations by elimination method.

Step 1:

Eliminate one variable by using two pairs of equations.

$\"\"$

Add the 2^nd and 3^rd equations to eliminate a variable.

$\"\"$

Step 2:

Solve the system of two equations containing $\"\"$ and $\"\"$ to find $\"\"$ value.

$\"\"$

The equation $\"\"$ is always true.

Therefore, there are infinite number of solutions.

$\"\"$

The solution of the system is infinte.
